The Rope Wrench friction device by ISC allows climbers to ascend, descend and work the tree 'single Rope" with their favorite friction hitch. While the Rope Wrench ZK-2 is not for use as your life support device, it places a bend in your climbing line and takes just enough pressure off your hitch, allowing you to climbing on your friction hitch SRT with greater ease.
The strength of the Rope Wrench for arborist work comes in how easily it allows you to enter the tree with a foot ascender or by footlocking for the long climb, then switch to working the tree as if you were using Doubled Rope but without having to switch out more gear than your foot ascender.
The ISC Singing Tree Rope Wrench has become a well established, popular tool within the production climbing industry and in tree climbing competitions.
The Rope Wrench provides an 'S' bend in the rope above the hitch cord. This effectively provides a contained double rope system, on a single rope, which shares the user's weight between the Wrench and the hitch. This allows the operation of the hitch, without the need for a double-rope system. The Rope Wrench allows easy horizontally movement, with greatly reduced friction on re-directs (compared with DdRT).

SRT for less
I cut mostly hardwoods so I use hitch cord. The rope wrench lets you use your favorite hitch on a single leg of rope. Its mid-line attachable and can transition to DRT in a couple minutes. Also, its half the cost of most mechanicals.
